LAWN-SPRINKLER.

SPECIFICATION forming part of Letters Patent No. 556,610, dated March 1'7, 1896.

Application led May 25, 1895. Serial No. 550,650. (No model.)

T0 a/ZZ whom t nfl/cry concern:

Be it known that I, CHARLES A. ASHTON, of Piqua, in the county of Miami and State of Ohio, have invented a new and useful Improvement in Lawn-Sprinklers, of which the following is a full, clear, and exact description.

My invention relates to an improvement in lawn-sprinklers; and it has for its object to provide a device of this description which will throw a gentle yet effective spray and wherein the spray will distribute itself evenly over a maximum of surface; and another object of the invention is to construct the sprinkler in such manner that it will be simple, durable, and economic, and whereby, further, the sprinkler may be expeditiously and conveniently cleansed from any obstruction that may lodge in it or interfere in any manner with the efficiency of the spray.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth and pointed out in the claims.

Reference is to be had to the accompanying drawings7 forming a part of this specification, in which similar characters of reference indicate corresponding parts in both figures.

Figure l is a side elevation of the improved sprinkler, and Fig. 2 is a longitudinal vertical section through the major portion thereof.

In carrying out the invention the base A, which may be of any suitable material or of any desired shape, is made hollow and is furthermore preferably provided with a tubular branch lO at one of its sides. The top of the base is adapted to receive the lower end of a pipe 11, which is of a predetermined diameter, and the tapped portion of this pipe extends within the chambered portion of the base, being connected with an elbow 12 or its equivalent, to which elbow a short length of pipe 13 is attached leading out through the tubular branch 10 of the base, and to the outer extremity of this short length of pipe a hose-coupling 14 is secured in any suitable or approved manner.

A reducer 15 is placed upon the upper end of the stand-pipe 1l, since the said pipe is to be arranged in an upright position, and this reducer receives a second stand-pipe 16 of less diameter than the main stand-pipe 11. The reduced stand-pipe 16 is adapted to receive and support a spreading-head B, and said head consists of a base-section 17, adapted to receive the reduced stand-pipe 16 and provided above said pipe with an enlarged bore 18, as illustrated in Fig. 2, while the top of the base is flanged and counterbored to receive the lower end of a closely-coiled spring 19, the said spring being preferably of helical shape.

The counterbore or seat for the spring 19 is of much greater diameter than the chamber 1S in the base of the spraying-head, so that the lower end of the spring may rest upon said base, and this portion of the spring is made fast to the base of the spraying-head by means of solder or equivalent means.

The spring 19 is surmounted by a cap 20, which is flanged and counterbored to receive the upper portion of the spring, and this portion of the spring is secured to the cap in any approved manner. The cap is likewise adapted for the reception of a plug 21. This plug is providedwith a bore 22, which extends from a point near its upper end through its lower portion, while in the top of this cap a reduced bore or channel 23 is made, adapted when the water is turned on in the sprinkler to emit a fine thread of water-spray up in the air, as is clearly shown in Fig. 2.-

The plug is readily removable from the cap of the sprinkling-head, so that in the event any foreign matter should lodge within said head the volume and force of water passing through the stand-pipes will quickly dislodge such material.

The water will be forced out through the interstices of the spring and the small opening 23 at the top of the plug and will fall upon the surrounding surface in like manner as a miniature fountain.

It is evident that a sprinkler constructed in the manner above set forth will not only be economic, but will likewise be thoroughly effective, since a horizontal spray may be proj ected from the coiled section of the sprinkling-head, while a vertical and dropping spray will find exit from the top of the device.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent- 1. In a lawn-sprinkler, a spraying-head, the

same consisting of a base having a bore vin two IOO diameters, a helical closely-coiled spring secured at its Wider end to the said base above the enlarged port-ion of its bore, a cap secured to the contracted end of the said spring, and an apertured plug removably secured in the said cap, as and for Jalle purpose specified.

2. In a lawn-sprnkler,a spraying-head, oonsisting of an apertured base having a flanged upper end, a coiled spring on the base Within the flange thereof, and a cap having on its 1o under side a 'flange surrounding the upper end of the spring, and provided. with an apertured plug, substantially as described.
